Will any hydraulic fluid work for my Boss snow plow?

    I have a brand new Boss Power V plow. While messing around with it today it was chattering. I read that this can be caused by low hydraulic fluid.

    I checked the fill port elbow thing and I could not see any fluid. So I guess they didn't fill it all the way up.

    I will need to use the plow in the morning and the Boss plow dealer is closed today.

    Does it matter if the hydraulic fluid I use is not Boss specific? There is a Fisher plow dealer I could probably get some fluid from tonight.

    if you can't get the Boss fluid you can use Western or Meyer or Buyers low temp hydraulic fluids

    So the fluid the fisher dealer has probably won't work?

    You can also use transmission fluid.

    Lots here will botch and moan at me, but i have done it before without problems and actually carry 1L bottles in every truck.

    If you do this in a Meyer pump, it voids the warranty doesn't it? I am sure it works but.......

    Yes you can because the viscosity is relatively the same.
    You sir get a gold star for such a good answer.

    Not at low temperatures it isn't. ATF is up to 11 time thicker than dedicated plow fluid (or fluids meeting the same specs as such) thus increasing amp draw on the electricals both on the plow and truck side. We've fixed many issues over the years simply because the owner was running ATF. On the Boss's specifically it's normally related to wing relief issues. Thicker fluid simply doesn't work as intended with them and they believe it's a problem in the hydro manifold when in actuality it's the fluid.

    Guys will spend $6000 on a piece of equipment and then run it on $3 qt fluid...to save $14. :rolleyes:

    OP was in a pinch.

    If you do not have/carry hydraulic fluid you can find ATF at a gas station in the middle of the night.

    If it gets you thru the night, then the long term fix it later.
